RecyclerView多种item类型头部底部

想要定义RecyclerView多种item类型头部底部,就要重写RecyclerView.Adapter

getItemViewType 方法  RecyclerView.Adapter 代码简单明了 话不多说先看效果再看代码





1.RecyclerView 添加不同item的方法  就是在getItemViewType定义不同类型

   @Override

    public int getItemViewType(int position) {

        if (position == 0) {

            return IS_HEADER;

        } else if (position == data.size() + 1) {

            return IS_FOOTER;

        } else {

            return IS_NORMAL;

        }

    }

2.显示不同类型的item View,以及解决RecyclerView在XML 中设置MATCH_PARENT无效

    @Override

    public ListViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        if (viewType == IS_NORMAL) {

            View view = View.inflate(mContext, R.layout.home_fragment_item, null);

//要从代码中手动动给出MATCH_PARENT

            view.setLayoutParams(new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));

            return new ListViewHolder(view, IS_NORMAL);

        } else if (viewType == IS_HEADER) {

            View view = View.inflate(mContext, R.layout.home_fragment_header, null);

            view.setLayoutParams(new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));

            return new ListViewHolder(view, IS_HEADER);

        } else if (viewType == IS_FOOTER) {

            View view = View.inflate(mContext, R.layout.home_fragment_footer, null);

            view.setLayoutParams(new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));

            return new ListViewHolder(view, IS_FOOTER);

        }

        return null;

    }
